WeatherFlash liquid flashing and joint filler is used to prepare and seal exterior wall rough openings and detail joints as part of the WeatherTech air and water barrier system.
WeatherFlash is applied to exterior wall assemblies where it functions as part of an air and water resistive barrier system. WeatherFlash is an all-purpose, liquid applied flashing used in construction applications to bridge dissimilar materials and to create weather resistant, fully adhered pan membranes in window and door installations. Liquid Flashing can be applied over surfaces and substrates that have been prepared per the WeatherTech Guidelines. WeatherFlash bonds to most construction materials, such as aluminum, brick, concrete, wood, vinyl, exterior gypsum board, and various other construction substrates.
